To all whom it may concern:

Be it known that we, ALBERT F. Boon- WELL and V-Io'roR W. PAGE, citizensof the United States, residing at Bristol, county of Hartford, Stateof"Oonnecticut,,have in vented a certain new and useful Bell, of

Whi'clrthe following is a full, clear, and exact description, such aswill enable others skilled in the art to which it, appertains to makeand use the same, reference being had to the accompanying drawings,forming part of this specification. p, p t One object ofour invention isto provide a bellso constructed and operated that the operator mayreadilycontrol the same.

A further object is to provide a plurality of means for operating a belleither interchangeably or simultaneously.

A further object is to provide means for accelerating the speed of themoving member of said bell Without stopping said moving member. 1 v

To these ends andyalso to improve generally upon devices of thecharacter indicated,our invention consists in the various mattershereinafter described and claimed.

In the accompanying drawings: I r t Figure 1 is a lateraliview of ourdevice, partially in section; a t ,7

Fig. 2 is a front view in crosssection;

Fig. 3 is a side view of one clutch mem- I ber;

Fig. 1- is a lateral view ofour segment;

r Fig. 5is a front view, in cross section, of.

ourdriving sleeve; p r Flg. 6 71s a front, View, lncross-sectlon, of

3 our driving clutch member? our striking member; and

Fig. 8 is a modification, in cross-section; Referring to the drawlngs asthe ,-1llus-,

, trated' embodiment of-the invention, the device is adapted to -belocated preferably, on

Fig. 7 is a lateral view, in crosssection, of

ing said rotatable bell members is as follows. A handle 3- for operatingthe bell, positively secured to a segment Whichinturnis pivoted as at 5%to a, stud extending laterally from' said frame The segment preferablyex, tends approximately 1120" and has a rack -6 thereon engaging, andadapted: to drive, an intermediate gearingr 27= and thereby a drivingsleeve -7 which is mounted on the axle 2,-. Qn the surface of thedriving sleeve is provided a worm, 8 whichengages a complementary Wormrecess in a driving clutclrmernber It will be seen that, as the drivingsleeve 7 is propelled, the worm, due to the tendency lof the 1 drivingclutch member; to, lag behind the clutch sleeve 7 on account of; themembers inertia tends to screw out of p the grooves ,ofthe drivingclutch'member and thereby causesthe driving clutch member -9 to havealateral motion, and its diagonal, clutch surface, as at I1Q, when movedlaterally, frictionally engages a correspondingfdiagonal clutch surface110+ on a bell. sleeve '11-, so that when the diagonallsurfacles meet,both the bellsleeve 11-Y, the driving clutch member 9, and the drivingsleeve -7 are operated by the movement of the segment so that they allrevolvetogether about the axle --2, p p The bell is preferably dividedinto two members, the innermember and the outer member l3 both of whichare; preferably, positively secured to said bellsleeve ,l1-%-, all ofsaid partsbeingpreferably mounted on ball bearings 34 and (Fig. 2), andbeingheld. in proper location byla 1ocl:nut,-1t ,"on the end of saidaxle, {2 and acting to force the outer race member of; the bearing 35against the shoulder 36 of the bell sleeve 11. In this way the bellisgiven a demountable structure as the bearing is (letachablycarried uponthe spindleQahdthe sleeve is detach- J l ably carried upon bothbearings. The bell and the bell'sleeve v-llmay be, secnred together-inany suitable'manner and, for convenience of manufacture, it is preferredto, have them separate but movable together and theyamay beItermed amovable member- In he opera ion f u be l, as 9 11 as, the segment f hasreached the end of its stroke,'or for any reason the segment and itshandle 3 are stopped, the m'othe bell itself. Consequently, as soon asthe clutch is released,the bell members continue o tat f ee f m th in utsh ber '9 until the operator desires again to dr've the bellby means ofthe handle 3 a's described. i I

It is preferred to'have it possible for the bell members to continue torotate and be continually propelled, necessary, by another means and, ifdesired, either interchangeably or simultaneously with the above saiddriving means. i i

I The 0th r convenient and preferable ans, o t t aid b h Wh h P f r ablyrotates the bell somewhat slower than the above a d dri n 'me h i s f hQs Pre e a t' t lever nd 9f e rame l-,' p tv de an x eh ieh -l5-+ wh hhas a bushing therein, as at '-1 6- adapted to carrya shaftl7. Thisshaft l7 may be] pe ate i an s abl man r, ut a y b i h sl'wit exib h -1Whi h. c s e p rat b at? suitable means in the vehicle. At the site; endof the shaft {-17 we provide a pinion 1 8 which in turn engages teeth n.i s l9-' P si ely cur d; a at 0;'t h hel slee l n h r by'the bell membermay be rotated continually, or as desired, by means of the said h t fcou thi means f P- rat ng the ha .7 m e i o in l p a on r in tem o a yOp a es a h driver desires, preferably being controlled y hy u t bl meahh ng men t eta WithJ a Y i f' he pe o t e l eve s te e ts ated by mean$1 91 r am 6 as. tha rs de rib d the e 9 a S d. ea er a ha ive t by meas of e haft .I,' We o ide as a ma fe clutch member 28, Fig. 3,preferably loca ed a a sa raeme are. het eeh said shaft and its dr vingmeans, so that,

e t hit' 'h 28 is releasedjthe driv is mean such a fle shaft 47 thonglgiattached thereto, may have less speed than the shaft 17 ,'which is inconi ial en a emen wi th 'ih 'e m mbers of our bell. On the other handif the speed of the shaft -17' becomes less than that of the flexibleshaft 17-, the clutch -28 will automatically take hold and drive theshaft l7. As a preferable form of construction, our clutch -28 has aninner member 29 secured to our flexible shaft 17 and an outer member 30secured to our shaft 17. The outer member 30 has preferably a pluralityof eccentric surfaces up which surfaces movable members, such as balls31, ride to frictionally' engage both the inner and outer members whenthe inner member moves comparatively in one direction. When the innermember is moved comparatively in the opposite direction the balls 31 arereleased and the inner and outer members move free'from each other.

Oonsequently,-it will be seen that we provide two means of propellingour bell members which may operate simultaneously or separately at theconvenience of the driver. of the vehicle.

The sounding mechanism of the bell is as follows: On our innerbellmember 12, preferably integral therewith, we provide a lug -21. and onour outer bell member l8 we provide a similar lug 22-. These lugs arepreferably arranged at opposite sides ofthe bell itself and are adaptedto be struck a blow alternately by hammers 25 and 26 on a striking arm23 to sound the bell or gong. This striking arm Q3 is preferably pivotedto said bell sleeve 11 by means of a bearing 24 and is adapted to hangby gravity preferably within the lower part of the bell with the'hammersin the path of the lugs on the bell members. The bell members areadapted to rotate so that the lugs -21 and -2:2-, as they revolve,alternately meet the striker to sound the bell. On the lower end ofourstriker 23 we preferably arrange a transversebolt 2 l which carries thehammers 25 26 loosely mounted thereon, so that they slide radially backand forth toward the center of the bell as they meet the lugs 2l and 22when the bell rotates, whereby a clear, loud, distinct tone is therebygiven to the bell without impeding themovement of the same, when thebell members are driven by either ofthe above referred to driving means.

As a modifiedembodiment of our invention, in Fig. 8., the bell members-12 and l3f are preferably stationary while striking arms 23 arepreferably adapted to revolve therein to deliver blows on the lugs -2land 22- The striking arms 23* extend from and are preferably integralwith a ring 32"on one side of which there is an inner flange 33. On theopposite side the ring is preferably threaded to an external flange -11on the sleeve +11? and'is thereby detachably mounted in place on thebearing 2 l abutting the shoulder 2- 011 the shaft -2, the strikingmembers thus (being secured to the sleeve -1l to revolve therewith onthe said bearing '-2 l The bell member -13 is spaced from the bearing24:" by the sleeve 87 and the parts are held assembledjupon the axle 2by the nut The bearing is shown as of the unit-handling type i. 6., it,by virtue of itsown construction, remains assembled so that its racemembers and antifriction members will not separate and fall apart. lVepreferthis type of hearing as, with it, no means,other than the bearingitself, is needed to keep the arm *23 and the ring 325 mounted upon theaxle. f

In the modified form of Fig. 8 we may, as illustrated, use the frame 1,axle 2, handle 3, segment 4, pivot 5 and rack 6 practically as in Fig. 2but in this modified form We use a shaftQY operatively connected withthe rack 6 and such shaft, bymeans of the gear 27 drives the drivingsleeve 7, the sleeve 7, by its worm 8, being connected with thelaterally shiftable taper-clutch element 9 adapted to engage thetaper-clutch surface of the sleeve 11? at 10 Thus, with this structure,the arms 23 are caused to ro tate to bring the hammers 25 and 26 intocontact with the strike-lugs of the gongs.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent isi 1.
